When ordering spare parts, the serial number of the motor and its full type designation and product code, as stated
on the rating plate, must be specified.
1.8.2 Rewinding
Rewinding should always be carried out by qualified repair shops.

Bearing replacement is described in detail in a separate instruction leaflet available from the ABB Sales Office.

must not be changed.
1.9 Environmental requirements
Most of ABB's motors have a sound pressure level not exceeding 82 dB (A) (± 3 dB) at 50 Hz.
HDP motors are by default supplied by frequency converters therefore the sound pressure levels are measured at
their rated speed only.
When motor(s) need to be scrapped or recycled, appropriate means, local regulations and laws must be followed.
